Heisenberg was born today
In nineteen hundred one
And ever since, our Universe
Has been a lot more fun
What we thought was certainty
Turned out to be uncertain
As though a giant hand had come
And pulled aside a curtain
Revealing a much deeper world
Where everything’s in doubt
And much of what we thought we knew
Was all turned inside out
Heisenberg was born today
And everything’s now fuzzy
All ’cause Werner Heisenberg
Was born today — or was he?
